Abstract

Methods for processing waveforms may include using temporal descriptor information about an input waveform to selectively request a segment of the input waveform that, when processed by a filter, produces a segment of an output waveform. In an illustrative example, waveform descriptor information may be used to request data to perform unary or filtering operations, or to perform one or more processes that involve at least one additional waveform. In combination with a filter descriptor that identifies, for example, upsampling factor, delay samples, and startup samples, complex waveform operations may be processed by selectively pulling input waveform segment data to generate a segment of the output waveform. In embodiments that process sequential waveform segments, filter tap states may be initialized using state information from processing of a previous waveform segment.
